We know at this point that the engineers at MAHLE Motorsport don’t sleep. How can they? It seems like every week they are raising the piston game with new releases, innovative products, and components to help their customers go faster with more reliability. That’s exactly the case here with the company’s new PowerPak Piston Kits for S55 and N55 3.0L BMW engines.
There are millions of BMW enthusiasts out there and they are hungry to make more horsepower than they ever have before. By adding or increasing boost for turbocharged applications or ramping up the compassion of naturally aspirated ones, that power can be found and found reliably by using these pistons.
Neat stuff and the whole story is below!
Here’s the full story from MAHLE Motorsport!
MAHLE Motorsport Expands Power Potential for 3.0L BMWs – PowerPak Piston Kits Now Available for S55 and N55 Engines
Fletcher, NC, (July 28, 2020) –Naturally aspirated or turbocharged, MAHLE Motorsport now provides BMW engine builders a solid choice to build power for 3.0L BMWs with the introduction of a PowerPak Piston Kit designed for either the BMW S55 or N55 engine. As manufacturer of the world’s most winning race pistons, this shelf stock PowerPak Piston kit is specifically engineered for high horsepower applications- vehicles with nitrous or power adders that greatly increase boost pressures.
Manufactured from 2618 aluminum alloy recognized for its high temperature strength characteristics each piston is dual coated with a dry lubricant Phosphate coating and a GRAFAL® skirt coating to reduce drag and wear by providing additional cushioning to absorb hard contact between the piston skirt and cylinder bore. Available either in the factory compression ratio 10.2:1 or 11:1 for the N55, the piston features larger valve pockets to accommodate up to +1.0mm larger valve diameters and has a 1mm deeper valve pocket for performance camshafts.
A 1.0, 1.2, 2.8mm oil ring set is included in addition to heavy duty steel pins and Circlips. MAHLE’s new HV385 steel thin ring design delivers excellent ring-to-cylinder sealing with low mass and an extended RPM range without loss of ring stability. The top ring groove is hard anodized to protect against micro-welding. Both the top and second ring lands are optimized for higher piston speeds and boost pressure.
